Benefits of CO2 Supplementation in Planted AquariumsThe CO2 effect
Aquarium plants use light and carbon dioxide during photosynthesis, the process by which they feed. Fish and bacteria in your aquarium give off CO2 through respiration, but in a planted aquarium, the CO2 created from that process is not always sufficient for optimal plant growth. A CO2 unit supplements your freshwater-planted aquarium by increasing the amount of carbon dioxide available for your plants in the aquarium water.

With proper CO2 levels, your plants will be healthier and grow faster. A low CO2 level will essentially starve your plants and limit their growth. Keep in mind that the more plants you have, the more they are going to be competing for carbon dioxide, and the greater their need will be for supplemental carbon dioxide. Like most things in the aquarium hobby, balance is required with CO2. Just as it is not healthy for planted aquariums to have low CO2 levels, it is also unhealthy for them to have high CO2 levels. Excess carbon dioxide strips the water of beneficial oxygen, reduces pH levels, and can throw off water quality. Be sure to routinely monitor your water parameters, perhaps even more closely, if you are employing the use of a CO2 unit.

The two basic requirements for healthy aquarium plants are light and proper carbon dioxide levels. Installing a CO2 system is essential to prevent low CO2 levels and to maintain active plant growth. Learn more here.

Every organic molecule of every living organism is predominantly carbon based. Given this simple fact, it becomes clear why carbon dioxide plays a pivotal role in the planted aquarium. Greg Morin, President/CEO, Seachem Laboratories, Inc. explains.

Read this before purchasing.
Overall I would say that this is not a bad product. But there are a few things to know before buying. 1) It's flimsy. Don't try to open it to put water in it. Broke one of mine. Instead "suck" water into it. Put the intake tube in water and suck on the blue elbow. The water goes in with no problem. It's much easier that way. And you won't risk breaking anything. Not to mention that black cap is a bear to get out. 2) I would not recommend using this with an UpAqua inline co2 diffuser. The diffuser requires too much pressure to allow co2 to pass through. The back pressure will cause the top to pop up and leak. If you get this bubble counter I would say use it with one of those "in-tank" diffusers with the ceramic stones.

Poor Quality
This product is not worth the money. It is poorly constructed and the airline connection broke the first time I disconnected the CO2 line. The suction cups that are supposed to hold the unit to the aquarium would not hold for more than a minute.

Do Not Buy
I have owned two of these bubble counters. I returned the first one and threw away the second one. They leak CO2.

Not Happy
I too received this bubble counter with a co2 system. I like the rest of the system, but this seems to be the one flaw. It loses water too quickly, which would be fine, I can add water once a week. Problem here is you can't get the top off or back on easily enough. I just broke mine trying to put it all back together again. I definately won't be spending $30+ on another one of these. There needs to be a better system, I may get creative & see if I can design a better one.
